I'm not a great fan of loyalty cards because of the bulge they make in my wallet. I am continually being asked if I have such-and-such a card when making a purchase and have to admit that I do indeed have one, but not with me. In most cases the loyalty cards are credit-card format with an embossed number and swipe strip; or, in some cases, they have a bar code.
Here's a wonderful opportunity for some enterprising iPhone app developer. Wouldn't it be great to store all your loyalty card information in an iPhone app? All you would need to do would be open the app and have the retailer read the barcode or whatever from the phone. The technology exists and would be welcomed by all shoppers. I wouldn't mind a percentage of the proceeds for contributing the idea.
